When is a move about Carlos Lehder Rivas going to be made?

Carlos Lehder Rivas character was depicted in the movie "Blow", what is interesting is that Mr. Lehder was listed as the 7th richest man in the World during the 80's. And is still alive (unlike Pablo Escobar) and has lived one of the most interesting lives of any Drug Lord and yet his name is not a common household name as Pablo Escobar.
